Make sure to mention how the problems are structured—step-by-step solutions, multiple approaches? If the solutions are straightforward without much explanation, that's a con. Also, if the PDF has formatting issues, like poor diagrams or low-quality scans, that could be a drawback.
Accessibility: The PDF being readily available online might be both a point in favor and a potential issue with copyright. Need to mention that downloading it if it's pirated is not recommended, but if it's a legitimate copy, it's accessible.
Depth of explanation: Does it go into sufficient detail? Sometimes textbooks are criticized for being too concise. If Satya Prakash's book is thorough, that's a plus. However, if it's more of a reference with notes rather than an in-depth study guide, users might find it lacking for building a strong theoretical foundation.
Problem sets are usually a key part. I should highlight whether the problems are varied, from simple to complex, and if there are enough of them. Also, if the explanations are clear. Maybe some users find the problem solutions a bit brief, so that could be a point to mention.
Language and clarity: The book uses clear and concise language? Avoids unnecessary jargon. But since it's for Indian students, maybe the approach is tailored to the Indian education system, which is good for local readers but might not be as suitable for international audiences.
First, the basics: the book is in PDF format. I should mention that it's a compilation of notes and problems, maybe not just a textbook. Users might be looking for its accessibility, so the PDF aspect is important. I need to talk about the content. What topics does it cover? Electricity and magnetism basics, Maxwell's equations, electrostatics, magnetostatics, electromagnetic waves, perhaps circuits, current electricity—those are standard.
Wait, I should check if there's any recent information about this book. Sometimes textbooks become outdated. If it's a standard reference since the 60s or 70s, maybe it's a classic but might not cover modern advancements. Also, verify if there are any updated editions or newer authors in the same field.
Reputation and popularity: How does it compare to other textbooks like Halliday & Resnick or David J. Griffiths? Satya Prakash is popular in India, so it's a good supplementary text. However, for those needing a primary textbook, a more comprehensive resource might be better.
